Senior advisers at top Wall Street firms are speaking to representatives of Deutsche Bank about ideas including a share sale and asset disposals, Bloomberg reported, citing people familiar with the discussions.

The banks are offering to help underwrite a stock sale to raise about 5 billion euros (S$7.7 billion), the maximum amount in discounted shares Deutsche Bank can sell without needing shareholder approval, Bloomberg said.

Market voices on:

The German lender is deliberating whether to sell the shares once it reaches a settlement with the US Department of Justice on a probe tied to residential mortgage-backed securities, Bloomberg said.

No final decisions have been made and the bank could decide against a capital increase, Bloomberg reported.

Deutsche is fighting a fine of up to US$14 billion from the US Department of Justice.

The chief executives of several German blue-chip companies have discussed Deutsche Bank's problems and are ready to offer a capital injection if needed to shore up Germany's largest lender, German newspaper Handelsblatt reported earlier on Thursday, citing sources.
